Comparison of several forms of disk storage showing tracks not-to-scale ; green denotes start and red denotes end. A CD-ROM drive without case The rotational mechanism in an optical drive differs considerably from that of a hard disk drive's, in that the latter keeps a constant angular velocity CAVin other words a constant number of revolutions per minute RPM.
With CAV, a higher throughput is generally achievable at the outer disc compared to the inner. It was a feature important for streaming audio data that always tend to require a constant bit rate.
But to Cheap colored paper no disc capacity was wasted, a head had to transfer data at a maximum linear rate at all times too, without slowing on the outer rim of disc.
This led to optical drives—until recently—operating with a constant linear velocity CLV. The spiral groove of the disc passed under its head at a constant speed.
Later CD drives kept the CLV paradigm, but evolved to achieve higher rotational speeds, popularly described in multiples of a base speed. For Blu-ray drives, base speed is 6.
Because keeping a constant transfer rate for the whole disc is not so important in most contemporary CD uses, a pure CLV approach had to be abandoned to keep the rotational speed of the disc safely low while maximizing data rate. Cheap colored paper switching to CAV requires considerable changes in hardware design, so instead most drives use the zoned constant linear velocity Z-CLV scheme.
This divides the disc into several zones, each having its own constant linear velocity. Without higher rotational speeds, increased read performance may be attainable by simultaneously reading more than one point of a data groove,  but drives with such mechanisms are more expensive, less compatible, and very uncommon.
Play media Opening the tray of a CD-RW manually with the help of a paper clip Current optical drives use either a tray-loading mechanism, where the disc is loaded onto a motorized or manually operated tray, or a slot-loading mechanism, where the disc is slid into a slot and drawn in by motorized rollers.
With both types of mechanism, if a CD or DVD is left in the drive after the computer is turned off, the disc cannot be ejected using the normal eject mechanism of the drive. However, tray-loading drives account for this situation by providing a small hole where one can insert a straightened paperclip to manually open the drive tray to retrieve the disc.
A small number of drive models, mostly compact portable units, have a top-loading mechanism where the drive lid is opened upwards and the disc is placed directly onto the spindle  for example, all PlayStation One consoles, portable CD players, and some standalone CD recorders all feature top-loading drives.
These sometimes have the advantage of using spring-loaded ball bearings to hold the disc in place, minimizing damage to the disc if the drive is moved while it is spun up. Some early CD-ROM drives used a mechanism where CDs had to be inserted into special cartridges or caddiessomewhat similar in appearance to a 3.
This was intended to protect the disc from accidental damage by enclosing it in a tougher plastic casing, but did not gain wide acceptance due to the additional cost and compatibility concerns—such drives would also inconveniently require "bare" discs to be manually inserted into an openable caddy before use.
There were also some early CD-ROM drives for desktop PCs in which its tray-loading mechanism will eject slightly and user has to pull out the tray manually to load CD, similar to the tray ejecting method used in internal optical disc drives of modern laptops and modern external slim portable optical disc drives.
Like the top-loading mechanism, they have spring-loaded ball bearings on the spindle.
Computer interfaces[ edit ] Digital audio output, analog audio output, and parallel ATA interface. Most internal drives for personal computersservers and workstations are designed to fit in a standard 5. Additionally, there may be digital and analog outputs for audio.
The outputs may be connected via a header cable to the sound card or the motherboard. At one time, computer software resembling CD players controlled playback of the CD. Today the information is extracted from the disc as data, to be played back or converted to other file formats.
Some portable versions for laptops power themselves from batteries or directly from their interface bus.
Drives with SCSI interface were made, but they are less common and tend to be more expensive, because of the cost of their interface chipsets, more complex SCSI connectors, and small volume of sales.
When the optical disc drive was first developed, it was not easy to add to computer systems. Early laptops simply had no built-in high-speed interface for supporting an external storage device. This was solved through several techniques: A sound card could often have two or three different interfaces which are able to communicate with cdrom drive.
A parallel port external drive was developed that connected between a printer and the computer. This was slow but an option for laptops.Our matte (see here for the pearlized) raffia ribbon is made of quality synthetic rayon and is not the cheap paper type.
Matte finish raffia on a roll gives a natural look with a smooth, flat color that many desire. Looks great on any package.
Raffia ribbon comes in a twisted together strand 1/4" in width, which can be pulled apart to expand to 1 1/4" in width for nice looking bows.
